AUTOMOBILE-LOCK.

Specification of Letters Patent.

Patented June 8, 1920.

Application filed June 26, 1918. Serial No. 242,000.

more commonly termed transmissions, there are employed either one, two,three or some times four shifter rods or devices, the movement of whichcontrols the various speeds of power transmitting ratios of which thedevice is capable, and in some of these constructions, mainly thoseemploying two rods, the rods or devices are set preferably in parallelspaced relation in the same horizontal plane, but this is notdesirableun some types of transmissions even employing two, three orfour rods or shifter devices, and in order to conserve space, it hasbecome the custom to arrange the rods or shifter devices in staggeredrelation, preferably in different horizontal planes, and it is thelocking of this arrangement of rods or shifter devices that the presentinvention is designed to accomplish, and wherein the rods or devices arealternately or successively locked from operative movement as the sameare so arranged as to not be simultaneously locked by a simpleconstruction.

\Vith the above mentioned and other ob jects in view, the inventionconsists in the novel construction and combination of parts hereinafterdescribed, illustrated in the accompanying drawings and pointed out inthe claim hereto appended; it being understood that various changes inthe form, proportion, size and minor details of construction within thescope of the claim may be resorted to without departing from the spiritor sacrificing any of theadvantages of the invention.

To more fully comprehend the invention, reference is directed to theaccompanying drawings, wherein- Figure 1 is a vertical sectional viewofthe preferred embodiment of my invention, illustrating particularlythe arrangement of the shifter devices and with the lock means inreleased or unlocked position.

Fig. 2 is a sectional view, taken on line 22 of Fig. 1, illustratingmore particularly the arrangement of the shifter devices.

Referring more particularly to the drawings, wherein like characters ofreference designate corresponding partsthe numeral 1 indicates asuitable gear casing or housing in which are mounted the variable speedgears 2, of any well known construction, and the same are preferablymounted to slide on a shaft 3, and are operated to move longitudinallyof said shaft or longitudinally within the casing to engage withcooperating gears therein by suitable shifter devices of any suitableconstruction, the form illustrated being the yoke members l operating insuitable grooves formed in the shoulders 5 projecting from the sides ofthe gears, said yokes being carried by the respective rods (3, which inorder to conserve space are arranged in different horizontal planeslongitudinally of the casing 1 in parallel spaced relation, said rodsbeing movable longitudinally of the casing and slidable in suitablebores 7 formed in a member 8, providing a guide therefor, and secured tothe casing in a hereinafter described manner.

Positioned intermediate the inner end of the member 8 and the wall ofthe casing 1, through which the rods 6 extend, is a suitable lock casing9 provided with bores 10 adapted to aline with the bores 7 and throughwhich the rods 6 are slidably mounted, the casing being secured. to thehousing 1 by suitable bolts 11, which also secure the member 8 to thewall of the member 1. The casing 9 is provided. intermediate the bores10 therein, and at right angles thereto, with a suitable recess or bore12, intersecting said bores 10, the upper end of said recess or borebeing enlarged and forming a chamber 13 open at its upper end.

Within the chamber 13, and adapted to eX- 1 tend within the recess orbore 12, is a longitudinally movable locking bolt 14 having an enlargedhead 15 at its upper end in which is mounted the laterally disposedlatch 16 capable of inward movement to unlocked position on the rotationof a locking barrel 1'? controlled by a suitable key operated lockmechanism 18 mounted in a recess in the upper end of the head 15.

A spring 19 forces the latch 16 outwardly and on the depression of thebolt 14, is received in a recess 20 in the side wall of the chamber 13.

' The upper end of thecasing 9, adjacent the enlarged head 15 of thelocking bolt, is provided with a vertical groove 21, through whichprojects the operating handle 22, extended laterally from said head 15,said handle providing a guide for the bolt during the movement thereof.

A, suitable coiled spring 23, positioned between the underside of thehead 15 and surrounding the bolt'let, is retained under pressure by asuitable washer 24 resting on a collar 25 projected inwardly into thechamber 13, and thus automatically restores the bolt 14 to unlockedposition on the withdrawal of the latch 16. The lower or looking end ofthe bolt 23'operating within the guide 12 is preferably receivable, onbeing I depressed, in suitable notches or grooves 26 formed in adjacentfaces of the respective rods 6, whereby on the depressing of the bolt14: the rods are selectively engaged, and thus alternately orsuccessively locked from operative movement.

The body herein referred to as being provided with openings for varyingthe gear shift devices or rods may be formed in the gear. case if sodesired and during the manufacture of the case.

Having thus described my invention, what I claim as new and desire toprotect by Letters Patent is An automobile motor transmission lockcomprising in combination with a transmission gear shift device, of asupporting secting said opening and the other end of Wl'UCh opens at oneend of said member, said bore provided in its side wall near its upperopen end with a longitudinally disposed slot, a locking bolt within saidbore and capable of longitudinal movement therein, said bolt beingprovided with an enlarged head, a spring for normally maintaining thehead of said bolt projected outwardly from the open end of said bore,said bolt adapted for manual depression to engage said gear shift deviceand lock the same from movement, an operating handle extended throughsaid slot and connecting with said enlarged head for preventing axialrotation of the bolt within said bore, a latch carried by the enlargedhead of said bolt for projecting laterally beyond one side thereof andadapted on the depression thereof for engaging within-a recess in saidbody, and lock-controlled means seated within said head and cooperatingwith the latch for releasing thesame, said latch and lock controlledmeans being movable longitudinally with said bolt.

In testimony whereof I have signed my name to this specification in thepresence of a subscribing witness. I

GEORGE C. JENSEN.
